'1 '0 all whom it mayconcern:

Be it known that I, GEORGE A. STaN'roiI,

provide an extremely strong and rigid ore crusher which will be formedof a few simple parts that will not easily getout of order and may bemanufactured at minimum cost. 5;} I

With the above objects .vi tion consists of certain novelaf structionand combination f p after fully described andj icl'a'imed understoodthat variOtiItiO'difi'ct n made in, the minor details of con'st-iiuwithin the scope of the'appended claims.

A "pair of postslfljare' se-- to the outer faces ofjthe eas h post being fixed 'to therel thef'ang which knee is rigidly 'securedjin-fz'p a castings 11 arefurther rigidly braced'by means of pairs of inclined braces 17, each iwhich cbyi the bolts 13 and 15 above"mentioned..-1 'Thej pair beingsecured at the lower ends to a related bed sill by a pin 18, and being secured at the upper ends to a related post by a pin 19.

Pivotally attached to the castings 11 and inclining oppositely therefromare castings for journaling the crushing and pulver izing rollers on theother side of the machine, these castings being adjust-able with respectto the castings 11 within certain limits aswill hereinafter appear, .inorder .tovary the space between the coacting crushing and pu'lverizingrollers to adapt] the machineto operate upon various ores.

able openings in the castings 20 and through hinge ears 22 on thecastings ll -and forms a a pivot for the castings 20. The castings 20are provided each with an extension 23 which extends below said pivotand bears upon the outer face of the related bed sill 'for a purposewhich willpresently be-described. .A pair of posts 24 are secured to--.the outer faces of the castings 20"ea'ch post being rigidly fixed tothe related "casting by ,bolts 25 and being further fixed to therelated. extension 23 by means of bolts 26.

A transverse shaft 21 is passed through suit -Forfned in each extension23 is an arcuate slot 27 having its center of curvature c0- "incidingwith the axis of theshaft 21', and

through each slot and a si iitableope iiing in I therelated bed sill astopbolt 2 81 s, passed. It, is now clear that when the castings 20 arerockedin either direction on their pivot slilaft 21, the bolts 2 8.willcontact with the withinwhich limits of movementthe cas'tings 20 may beadjusted to vary the space between the rollers carried by these castingsand the rollers carried by the stationary Scastings 11, to enablevarious ores to be most efi'ecti'vely operated upon. I a

f Journaled at the ends in,--the-stationary castings 11 is a series" ofequal-ly spaced apart superposed rollers substantially equal rollers 29,30 and 31 of the stationary casting in operating upon the ore. Theupperclogging.

most rollers 29 and 32 of both series are known as the first set ofcrushing rollers and vthese rollers are corrugated spirallylongitudinally of their length, and are rotated toward each other,whereby a continual grind or crush of the ore is effected without Theintermediate rollers 30 and 33 of bot-h series are known as the secondset of crushing rollers and these rollers are also corrugated spirallylongitudinally of their length and are rotated toward each other, and itwill be noted that by virtue of the divergency of the stationarycastings 11 and adjustable castings 20, the second set of crushingrollers are disposed nearer together than the first set, whereby the orewhich has been crushed-by the first set into irregular fragments iscrushed into still smaller fragments by the second set of rollers. Thelower rollers 31 and 34 of both series are known as the pulverizingrollers and these rollers are rotated toward each other and have theircylindrical surfaces smooth, and by virtue of the divergency of thestationary and adjustable castings, the pulverizing rollers normallycontact with a resultant pulverizing of the ore during its passage downbetween these rollers.

Any preferred means for actuating the series of rollers carried by eachpair of the castings may be employed, but preferably the series ofrollers are actuated by related trains of gears 35 and 36 which aredriven by a common driving gear 37 carried by a stub shaft 38 which is journaled in a bracket 39 carried by one of the ground sills 10, whichshaft in the present embodiment of the invention. is illustrated asbeing driven by a sprocket gear 40, it being understood that anypreferred driving means may be employed without departing from thespirit of the invention.

For adjusting the adjustable castings 20 and locking the samein-adjusted positions, I provide a pair of links 41 which extend alongthe outer faces of the posts v14 and 24 .near the upper ends of thelatter, each link being pivotally connected at one end to the relatedend of the above mentioned pin 19 carried by the post 14 of the adjacentstationary casting l1, and having a longitudinal slot 42 near theopposite end which slidably receives a block 43 which carries a pin 44that is secured to the related post24 of the adjacent adjustable casting20. A feed screw 45 carrying a hand wheel 46 is threaded through the endof the said link 41 and is engaged at the tip with the outer end face ofthe said block 42. Upon the feed screws being retracted, the weight ofthe adjustable castings 20 causes the castings to follow the feed screwswith a resultant spac ing apart of the crushing and pulverizing rollersto a greater extent than normal, and conversely upon advance of the feedscrews nected at the upper ends to the related pinv 44 and beingconnected at the'lower ends by a plate 48 which is engaged with a rackbar .49 carried on the top face of the related bed sill. The two pairsof props 47 are in the nature of strong rigid rods capable of withstanding the severe shocks and jars attendant upon the crushing andpulverizing of the ores during passage through the rollers.

A hopper 50 is secured to cap rails 51 and 52 which connect the tops ofthe posts 14 and 24 respectively, this hopper being designed todischarge its contentsinto the space between the first crushing rollersthe ore feeding down by gravity between the rollers to the second set ofcrushing rollers and from thence to the 'pulverizing rollers asordinary. The hopper is braced on one side by inclined braces 53 thatare con-' nected to the posts 14 and is braced on the opposite side byvertical braces 54 that are connected to the bed sills 10.

For housing the rollers, both posts 24 are connected by end walls 55 andboth posts 14 are connected by end walls 56. The posts14 and 24 on eachside of the machine are connected by side walls 57 and 58 respectively.The casing thus formed positively prevents escape of the ore until ithas passed through the pulverizing rollers.

From the above description it will be seen that I have provided anextremely strong ore crushing and pulverizing machine,

which machine may be adjusted within cerores, and furthermore that thedevice is formed of a few simple parts which will not easily get out oforder.
